• Core Function: Inductors store energy dynamically in the magnetic field of a DC-DC ...

Key Takeaways: Power supply architecture selection starts by comparing input and output voltage ranges. If Vin always exceeds Vout, use a buck converter; if Vin is always lower, use a boost; if the ranges overlap, use a buck-boost or SEPIC. Add an LDO...

Takeaway

• Desoldering removes a soldered component by re-melting the joint and clearing the molten solder with a solder sucker, desoldering wick, or hot air station.
• Multi-pin components (like DIP chips) can’t be desoldered pin-b...
